Toall {whom it may concern:

' Be it known that we, HARRY L. WHITE and vlirm vors' J. ROGERS, citizens of the United States of America, residing at Wheel ing, in the county of Ohio and State of West Virginia, have invented certain new and use ful Improvements in Envelope, of which the This invention relates to certain new and useful improvements in envelops,-and the invention has for its object the provision of pered with or openerhbefore the envelop is opened by the person for whom it is intend ed, or addressed. f I

Another object of this invention is to prof vide a simple and inexpensive envelop par' ticularly ada ted for transmitting valuable mails asfirst class matter. To this end, we have devised an envelop having an auxiliary sealing tongue, which to-' maintain an elastic band in a triangular form Within .the envelop, when the same is sealed, but should the-envelop be opened or ta1n-.

sition which can fbe readily determined before the envelop is openedr' i The constr uction of our improved enveh will be hereinafter more fully described in detail and-then specifically pointed out in the claims, and referring to the drawing accompanying this specification like numerals of reference designate corresponding parts throughout the several views, inwhichz- Figure 1 is a developed view of our improved envelop, Fig. 2 is an elevation of the same, partly broken away, illustrating the sealed, 3 is an elevation of the back of the envelop illustrating the envelop unsealed.

To put our invention into practice, we conend flaps 2, a bottom flapB, and a sealing flap 4. These flaps are constructed similar to the ordinary flaps of an envelop with the exception that the end flaps 2 are provided with angularly disposed tongues 5, while one of said flaps is provided with avertically diswith adhesive material 7. When the end flaps 2 are folded upon. the body ortion 1 of the envelop and held in their fol ed position by the bottom flap3 the vertically disposed tongue G-lies centraliyi of the envelop to en gage-the sealing flap; when the same is folded upon the "nod portion ofthe envelop;

. In connection with illustrat'h in Fig. 2- of the drawings. When the: envelop is to beclosed by the sealing flap 4,/one of the strands of the elastic band 8 is elevated and hooked over the end of the vertically disposed tongues 6, thus holding the elastic band 8 in a triangular form (se- Fig 3). The vertically disposed tongue 7 is then moistened, and as the sealing flap 4 is being sealed, said. flap will adhere to the tongue 6- and becomepart thereof. This tongue is of sufficient strength to maintain the sealin flap 4 in a closed position irre spective 0 whether the edges of said sealing flap are sealed;

Should the'envelop be tampered with, or surreptitiouslyopened, the same can bede tected by the position of the elastic band 8 Within the envelop. -When the sealing flap 4 is tampered with and the tongue 6 disenour improved envelop, r We use alcouventional form of elastic band 8 which. isicplace'd upon the tongues 5, 5, as

8 immediately assumes its normal position,

" and'as the band can be readily felt from the exterior of the envelop, the position of said band will readily-determine whether the envelop has been tampered with. The triangular harm of the band indicates that the envelo is in the condition in which it was orig nally mailed, while the straight position of the band illustrated in Fig. 2 designates that the envelop has been tampered with.

The tongues 5 can also be adhesivellzysecured t0 the envelop as illustrated in ig. 2 cl the drawing.

We do not care toconfine ourselves to the size or character of envelops constructed according to our invention and such changes as are permissible by the appended claims, may be resorted to without departing from the spirit and scope of the invention. What we claim and desire to secure b Letters Patent, is

An envelop comprising a body portion, end flaps, a bottom'flap, a sealing top flap, all of said flaps adapted to fold upon said body portion, downward angularly disposed tongue s carriedby said end flaps andextending with'their inner edges parallel to the ad jacent oblique edges of said carrying flaps, an

upward vertically disposedgummed tongue carried by one of said end flaps, an elastic In testimony whereof we afiix our signaband to engage over said ton es in a triantures in the presence of two witnesses.
